The FrSky Archer GR8, a great choice for big gliders.
This powerful 8 channel receiver features a hard plastic outer case and is shaped to fit in nearly all high performance sailplanes. It wouldn't be a glider receiver without a high precision variometer, built right into the receiver for hunting down those elusive thermals. Fine tune the settings in your FrSky radio to get audio tones to help track the lift and sink.
Want redundancy? Couple it with an SBUS capable receiver via the SBUS IN port and the receiver will automatically switch over to the second receiver should the GR8 have any issues getting a clean connection.
The radio will need to be running the most recent IXJT v2.1.x firmware to use Archer receivers!
